CY25561 is a spread spectrum clock generator (SSCG) IC used to reduce electromagnetic Interference (EMI) found in today's high speed digital electronic systems.

CY25561 uses a Cypress proprietary phase-locked loop (PLL) and spread spectrum clock (SSC) technology to synthesize and frequency modulate the input frequency of the reference clock. By doing this, the measured EMI at the fundamental and harmonic frequencies of clock (SSCLK) is reduced.

Dear valued customer,

Thank you for choosing our products. They come with all the know-how and passion that our engineers have put into it. As you probably already know, Cypress is now Infineon. This is a major step for our company, but also for the good of you.
